Evaluation of Maternal Serum 25-Hydroxyvitamin D Levels in Patients with Hyperemesis Gravidarum at Early Gestational Weeks

Aim: The aim of this study was to compare vitamin D levels between pregnant women with hyperemesis gravidarum before 12 weeks of gestation and healthy pregnant women at similar ages. Methods: Sixty pregnancies with hyperemesis gravidarum and 60 age compatible healthy pregnancies applied to our facility were included in the study. Demographic characteristics, maternal thyroid function tests and 25-Hydroxyvitamin D levels were evaluated. Student t test was used for the variables with normal distribution and Mann-Whitney U test was used to analyze the variables without normal distribution. Results: Only one pregnant woman had normal vitamin D levels (>30ng/ml), whereas 71 patients had deficiency (10-30 ng/ml), and 48 had severe deficiency (<10 ng/ml). The mean vitamin D level of the total 120 pregnancies was 11.9±5.00 ng/ml (9.92±3.67 ng/ml in case group, 13.88±5.38 ng/ml in control group). The mean value of vitamin D was found to be significantly lower in hyperemesis gravidarum. 45% (n=27) of the pregnant women had vitamin D deficiency, whereas 55% (n=33) of them had severe deficiency. Free T3 and T4 levels were significantly higher than the control group, and thyroid-stimulating hormone level was significantly lower. Conclusion: Vitamin D levels of pregnant women with hyperemesis gravidarum were significantly lower. Vitamin D deficiency should be considered in patients with hyperemesis gravidarum.

Abstract Children undergoing HSCT are at risk for vitamin D deficiency due to lack of sun exposure, the recommended use of sunscreen, dietary insufficiency, and the effects of medications such as glucocorticoids and calcineurin inhibitors. We assessed the prevalence of 25-hydroxyvitamin D (25-OH vitamin D) deficiency in pediatric post-HSCT patients in an outpatient oncology clinic during 4 weeks in May 2008. Patients found to have low 25-OH vitamin D levels were referred for dietary counseling and given supplementation or repletion as needed. 25-OH vitamin D and parathyroid hormone (PTH) levels were measured in 62 (88.6%) of 70 eligible patients. 83.8% of patients had a 25-OH vitamin D level less than the institutional lower limit of normal, 30 ng/mL. 29% of patients were 25-OH vitamin D insufficient with levels 20–29 ng/mL (range of 20–29). 54.8% of patients were 25-OH vitamin D deficient with levels <20 ng/mL (range 5–19). The prevalence of insufficiency and deficiency was similar between male (87.8%; 57.6%) and female patients (57.6%; 55.2%).The mean duration of days following transplant was 532.6 days (median 251.5 days). The mean age at transplant was 3.7 years (median 3.5 years). 47% of patients were female. 75.8% were Caucasian. 90.3% received allogeneic transplants. The underlying diseases were as follows: ALL (27.4%), AML/MDS (24.2%), bone marrow failure (11.3%), nonmalignant hematologic diagnosis (8.1%), solid tumor (8.1%), immunodeficiency (6.5%), lymphoma (6.5%), and other diagnoses (8.1%). 8 patients regularly took either an over-the-counter multivitamin or vitamin D supplement and all 8 patients had 25-OH levels less than 30 ng/mL. There was a negative inverse correlation of (r= −0.3, p=0.029) between PTH and 25-OH vitamin D. There were no significant associations between 25-OH vitamin D level and any of the following: corticosteroid or calcineurin inhibitor use in the preceding year, time from transplant, age at transplant, current age, or graft-versus-host disease. 25-OH vitamin D insufficiency and deficiency are common following pediatric HSCT. We recommend vitamin D screening for all post-HSCT pediatric patients. Further investigation is needed to identify potential risk factors for vitamin D deficiency and the long-term effects of deficiency on bone health and development.

Background: Alopecia areata is the commonest cause of non-scarring alopecia. Few previous studies have found correlation between AA and vitamin D deficiency, suggesting that vitamin D deficiency can be a risk factor for Alopecia areata. To compare serum vitamin D level between Alopecia areata patients and healthy controls; and to assess the relation between serum vitamin D levels and AA disease severity.Methods: This case control study included 30 newly diagnosed Alopecia areata patients. Thorough history was taken, detail examination was done and relevant findings were recorded in the standardized pro-forma. Their serum vitamin D (25-hydroxyvitamin D) levels were determined by competitive chemiluminescence methods; and were compared with that of age and sex matched healthy controls. Chi square test and Spearman’s rho correlation test were used for the inferential statistics using SPSS version 11.5. Results: There were 30 AA patients with mean age 28.37+10.07 years. Mean Severity of Alopecia Tool score was 3.56+3.50. Prevalence of 25-hydroxyvitamin D [25(OH)D] deficiency was significantly higher in AA group (83.3%) compared to the control group (53.3%) (P=0.01). Similarly, serum 25(OH)D level was reduced more in Alopecia areata group (12.84, IQR=8.87-20.47) than the control group (29.5, IQR=19.85-41.27) (P=0.06). There was inverse co-relation between serum 25(OH)D level and SALT score.Conclusions: Prevalence of serum 25(OH)D deficiency was significantly higher in Alopecia areata group compared to the control, with inverse co-relation between its level and Alopecia areata disease severity.

Abstract. Objective: To investigate the vitamin D status of pregnant women in the Liuzhou area and assess the effects of maternal vitamin D status on the cord blood of their newborns. Subjects and methods: This study included 8852 pregnant women and 2000 newborns. The serum 25-hydroxyvitamin D [25(OH)D] levels of the 8852 pregnant women and the cord blood of 2000 newborns were measured. Results: The results showed that the average level of 25(OH)D in pregnant women in this area was 76.55 nmol/L, and women in different trimesters had different vitamin D levels ( p < 0.001). The overall prevalence of vitamin D deficiency (<75 nmol/L) in pregnant women was 62.34%, and the proportion of severe deficiency (<25 nmol/L) was 0.25%. Vitamin D deficiency was more prevalent in the winter and spring than in the summer and autumn ( p < 0.001). Pregnant women who had regular vitamin D supplementation had higher levels of 25(OH)D than the women with discontinuous supplementation or no supplementation ( p < 0.001). Conclusions: Vitamin D deficiency was prevalent in pregnant women in the Liuzhou area. There were differences in vitamin D levels between the three trimesters and different seasons. For pregnant women with vitamin D deficiency, it is important to scientifically determine the appropriate level of vitamin D supplementation to ensure the health of mothers and babies.

Objectives: The objective of the current study was to examine the pathology test utilisation of 25-hydroxyvitamin D (25(OH)D) within an Australian inpatient psychiatric setting. Method: A retrospective audit of 300 random hospital files of those admitted as inpatients between Nov 2014 and Nov 2015 was undertaken. Data was quantitatively analysed and described. Results: The number of inpatients who had a vitamin D determination during their admission was 37/300 (12.33%). The mean vitamin D level of those tested was 51.63 nmol/l. Of those that were tested, 18/37 (48.6%) were mildly to moderately deficient. There was a statistically significant difference in age and length of stay between those that were and were not tested for vitamin D levels, p-value <0.001 and 0.017, respectively. In addition, a simple linear regression indicated a weak association between length of stay and vitamin D levels. Conclusion: This audit highlights vitamin D screening inadequacy. More research is recommended to establish tangible benefits of supplementation, while local practice provides valuable data for education and policy purposes.

Abstract Several studies have demonstrated that higher levels of vitamin D are associated with better prognosis and outcomes in infectious diseases. We aimed to compare the vitamin D levels of paediatric patients with mild/moderate coronavirus disease 2019 (COVID-19) disease and a healthy control group. We retrospectively reviewed the medical records of patients who were hospitalised at our university hospital with the diagnosis of COVID-19 during the period between 25 May 2020 and 24 December 2020. The mean age of the COVID-19 patients was 10.7 ± 5.5 years (range 1–18 years); 43 (57.3%) COVID-19 patients were male. The mean serum vitamin D level was significantly lower in the COVID-19 group than the control group (21.5 ± 10.0 vs. 28.0 ± 11.0 IU, P < 0.001). The proportion of patients with vitamin D deficiency was significantly higher in the COVID-19 group than the control group (44% vs. 17.5%, P < 0.001). Patients with low vitamin D levels were older than the patients with normal vitamin D levels (11.6 ± 4.9 vs. 6.2 ± 1.8 years, P = 0.016). There was a significant male preponderance in the normal vitamin D group compared with the low vitamin D group (91.7% vs. 50.8%, P = 0.03). C-reactive protein level was higher in the low vitamin D group, although the difference did not reach statistical significance (9.6 ± 2.2 vs. 4.5 ± 1.6 mg/l, P = 0.074). Our study provides an insight into the relationship between vitamin D deficiency and COVID-19 for future studies. Empiric intervention with vitamin D can be justified by low serum vitamin D levels.

Background: We postulated that the preoperative correction of vitamin D levels can significantly reduce the incidence of hunger bone syndrome among patients undergoing parathyroidectomy for primary hyperparathyroidism. Methods: We performed a prospective, randomized, open-label study on 102 patients with primary hyperparathyroidism and coexisting vitamin D deficiency who were scheduled to undergo parathyroidectomy. Patients were divided into the following two groups: group I which included 52 patients who did not receive preoperative vitamin D supplementation; and group II which included 50 patients who received cholecalciferol 1000–2000 IU daily or 50000 IU weekly until they achieve vitamin D levels >20 ng/mL (group IIa = 25 patients) or vitamin D levels >30 ng/mL (group IIb = 25 patients). Results: The incidence of hunger bone syndrome in group IIb was lower than group I and group IIa (8% versus 16% versus 23%, respectively); however, this difference did not reach the level of statistical significance (p = 0.22). Patients with hunger bone syndrome were significantly younger and had higher serum phosphorus, alkaline phosphatase, magnesium, and bone mineral density at baseline than patients without hunger bone syndrome. On the other hand, patients with hunger bone syndrome had significantly lower 25-hydroxyvitamin D at baseline than patients without hunger bone syndrome (p = 0.001). The ROC curve showed that the baseline level of serum 25-hydroxyvitamin D was not an independent discriminator of hunger bone syndrome (area under curve = 0.21 (95% CI: 0.06–0.34); p = 0.011). Conclusion: Preoperative course of vitamin D supplements has no preventive role on the postoperative incidence of hunger bone syndrome among patients with primary hyperparathyroidism and coexisting vitamin D deficiency undergoing parathyroidectomy.

Objectives: To determine the prevalence of vitamin D deficiency in 6- to 23-month-old children from 4 different ethnic groups, Han, Lisu, Hani, and Bai, in Yunnan Province of China. Methods: A large cohort of 938 young children aged 6 to 23 months who were living in Yunnan, China (23°28′-27°52′ N), were selected and recruited in this study. Venous-blood sampling was conducted in all the participants, and serum 25-hydroxyvitamin D [25(OH)D] levels were measured. The children’s physical status was measured. Results: General mean serum 25(OH)D level was 21.46 ± 7.95 ng/mL, which was obtained from a total of 938 cases. No significant difference was found in age, gender, height, and weight of participants from different ethnic groups. The mean 25(OH)D level was significantly lower in children of Lisu ethnic groups compared with that of Han and Hani participants, respectively ( P < .05). In addition, Bai children had lower 25(OH)D content than Hani children ( P < .001). Among the children with 25(OH)D sufficiency, the number of Lisu participants was significantly lower than Han children ( P < .001). Conclusion: The prevalence of vitamin D deficiency varied among the ethnically different children in Yunnan, China, and significantly fewer Lisu children maintained vitamin D sufficiency compared with other ethnic children. Recognizing these ethnic differences in treating children with vitamin D deficiency may improve the therapeutic outcome.

The Relationship

We aimed to describe the vitamin D status of young women living in two Chinese cities in the spring – Beijing in the north (latitude 39° north) and Hong Kong (latitude 22° north) in the south. We also examined the relationship between serum 25-hydroxyvitamin D and parathyroid hormone (PTH) concentrations to determine a threshold for serum 25-hydroxyvitamin D above which there is no further suppression of PTH. Finally, we examined whether dietary Ca intake influences this relationship. Non-pregnant women aged 18–40 years (n 441) were recruited between February and June. Fasting blood was collected and dietary intakes were assessed using 5 d food records. Mean serum 25-hydroxyvitamin D concentration was lower in Beijing than Hong Kong women (29 v. 34 nmol/l; P < 0·001). Vitamin D deficiency ( ≤ 25 nmol/l) was indicated in 40 % of Beijing and 18 % of Hong Kong women, and over 90 % of women in both cities were insufficient ( ≤ 50 nmol/l). Mean Ca and vitamin D intakes were 478 mg/d and 2·0 μg/d, respectively. The relationship between 25-hydroxyvitamin D concentration and PTH was linear throughout the range with a slope of − 0·36 (different from 0; P < 0·001; R 0·26), with no apparent threshold. There was no influence of Ca intake on the relationship between 25-hydroxyvitamin D and PTH concentration. Vitamin D deficiency is common and insufficiency is very common in non-pregnant women in Hong Kong and Beijing during spring. Serum 25-hydroxyvitamin D was inversely associated with PTH with no apparent threshold. Strategies such as vitamin D fortification or supplementation may be required.

e14653 Background: Results from large epidemiologic studies on the association between vitamin D and gastric cancer are controversial. Vitamin D significantly promotes apoptosis in the undifferentiated gastric cancer cell, but the prognostic effects of its levels are unknown. Methods: 197 gastric carcinoma patients who received treatment in the cancer centre of Sun Yat-sen University from January 2002 to January 2006 were involved in the study. The stored blood drawn before any treatment was assayed for 25-hydroxyvitamin D levels. The clinicopathologic data were collected to examine the prognostic effects of vitamin D. Results: The mean vitamin D levels of the 197 gastric patients was 49.85±23.68nmol/L, among whom 114(57.9%) were deficient in Vitamin D(<50nmol/L), 67(34%) were insufficient (50-75nmol/L) and 16(8.1%) were sufficient (>75nmol/L). Clinical stage (p=0.004) and lymph node metastasis classification (p=0.009) were inversely associated with vitamin D levels. The patients with high vitamin D levels group (≥50nmol/L) had a higher overall survival compared with the low vitamin D levels group (<50nmol/L)(p=0.018). Multivariate analysis indicated that vitamin D levels were an independent prognostic factor of gastric cancer (p=0.019). Conclusions: Vitamin D deficiency may be associated with poor prognosis in gastric cancer.
